    TUESDAY, April 22, 2014 (HealthDay News) -- Less than 10 percent of crimes committed by mentally ill people are directly linked to the symptoms of their disorders, a new study shows. "When we hear about crimes committed by people with mental illness, they tend to be big headline-making crimes, so they get stuck in people's heads," said study author Jillian Peterson, a psychology professor at Normandale Community College in Bloomington, Minn.

    WEDNESDAY, April 23, 2014 (HealthDay News) -- The deaths of well-known people offer an opportunity to educate the general public about disease detection and prevention, a new study suggests. Researchers surveyed 1,400 American men and women after Apple co-founder Steve Jobs died of pancreatic cancer in 2011 and learned that more than one-third of them sought information about his cause of death or information about cancer in general soon after his death was reported. About 7 percent of th...More >>

When you think of food allergies and severe reactions, most people focus on children and peanuts. But now, new research is showing that adults, particularly women and minorities are at risk, and the culprit is seafood.

According to a new study published in the Journal of Allergy and Clinical Immunology, seafood allergies are estimated to affect more than six million Americans, the majority of which are adults.

Dr. Scott Sicherer, the study's co-author, says women were almost twice as likely as men to be affected, with the highest rate reported by African Americans.

"Previously our studies looking at peanut and tree nut allergy showed that about one point two percent of the general population or over three million Americans, have peanut or tree nut allergy. We were shocked, essentially, to find that now over two percent of adults have seafood allergy."

Seafood allergies can cause life-threatening reactions, called anaphylaxis, a fact Meg Higgins learned when she had her first reaction in her early thirties:

"I actually had never had an allergic reaction in my life and only a few years ago, I went out with friends to dinner and I had salmon. Suddenly, my face started turning red, I felt like I couldn't breathe, my throat was swelling, and so I had to go straight to the hospital."

Typical symptoms of a food allergic reaction include hives, swelling of the lips, tongue or throat and difficulty breathing. Despite the potential severity, and unpredictability, of these symptoms, doctors say many adult patients tend to overestimate their ability to either avoid the food or deal with a reaction.

The study showed that patients went to the emergency room or consulted a doctor in about half of the reactions reported. For those that did see a doctor, less than eight percent were prescribed self-injectible epinephrine, which doctors say all patients at risk should carry with them at all times.
